Population assignment probabilities for 20 recently invaded brown rats (Rattus norvegicus) of unknown ancestry sampled on three islands in Haida Gwaii, BC.

Individuals were assigned following the methods of Rannala and Mountain [53] as implemented in Geneclass2 [54]. (Far/Mur) These samples were collected from Faraday and Murchison Island and grouped into a single unit based on a previous study [25]. Only reference populations with >0 probability of assignment in at least one individual are shown.
